T-molding should be 1-19/32" wide at the top. You will generally need 1" between the two floors to accommodate the U-Track and recommended expansion gap. This is for laminate floating flooring. For details type, "T-Molding" here - http://www.lumberliquidators.com/ll/flooring/Flooring101

Q:

How does this T molding fasten to the floor? I will be installing the wood laminate on a concrete slab floor in bedroom, transitioning to carpeted floor in hallway.
